Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8610138, here are decompositions:

37 + 8610101 = 8610138
71 + 8610067 = 8610138
137 + 8610001 = 8610138
139 + 8609999 = 8610138
151 + 8609987 = 8610138
211 + 8609927 = 8610138
227 + 8609911 = 8610138
239 + 8609899 = 8610138

Showing the first eight; more decompositions exist.
